Gold - Melting Points of Binary Eutectic Alloys

Au - Gold - binary eutectic alloys and melting points

The melting point of an alloy of two (binary) or more metals depends on the relative proportions of the ingredients. An eutectic mixture is the mixture at such proportions that the melting point is as low as possible.

Binary eutectic Gold - Au - alloys, with composition and melting points are indicated below:
